How to connect to ORACLE Database

Thank you Aksh for your quick reply.
I followed your advice:

NOTE: Connection String = Driver={Microsoft ODBC for Oracle};Server=10.3.4.xxx;

  1. After clicking test connection thats the error I’m getting:

  1. I have downloaded Oracle’s Instant Client and ODBC Driver as you can see in the screenshot below

  1. And I have set the Enviroment Variable PATH to the directory of the Oracle Instant Client extraction.
    Still it does not work. Can you please be more specific what am I doing wrong?
